Dc Header

I'm deciding between the usdm dc 4-1 ceramic header or the jdm one? How much of a difference in performance will the jdm header make?

you will need to add a 2.5 in. flange to the cat because of the JDM's larger collector.

DC is a Honda/Acura only company so of course they go good together

From what I've heard you should pass w/o a problem. I don't think the JDM header is carb legal though, shouldn't be a problem if you just get a heatshield on that sucker.
